    －You’re dropped __________ “s” in the word “across”.

    －Oh, you are right, __________ letter “s” should be doubled like this “cross”.

    A．a, a              B．an, a             C．an, the            D．the, a

     

    【答案】

    C

    【解析】

    试题分析：句意:在单词”across”当中,你丢了一个”s”.——哦，你说的对。想这个“cross”一样，这个字母“s”应该双写。结合语境可知上文泛指任何一个字母“s”故用不定冠词，s词首音素是元音，故不定冠词用an。下文特指某个字母，故用定冠词，选C。

    考点：冠词

    点评：冠词是一种虚词，一般用于名词前面表示特指或者泛指某一个。冠词的应用都用一定规则，熟记这些规则是解题的关键。不定冠词用在名词前，表示泛指任何一个。定冠词用在名词前表示特指某一个。在专有名词及表示泛指的复数名词前一般不要冠词，叫做零冠词。需注意的是不定冠词的用法是看词首音素，不是看首字母，如：useful首字母是元音，但是词首音素时辅音，故不定冠词用a；hour首字母是辅音，但是词首音素是元音，故用冠词an。

    LiLei: Hi, everyboby. I’m Jimmy. I like English very much, but I really need some advice on listening . Who can help me?
    Jenny:  Don’t get nervous before you start to listen to something. You need to relax. This will help.
    Dr.Smith:The first sentence tells a lot the whole passage.for example,if, at the beginning , you hear “Welcome back BBC news---”, you know you will hear a piece of news, not a children’s story, or a science report.
    Shirley: When you’re listening, try to do some thinking. For example, you can think of the following questions: What happened? When, Where and how? What was the result (结果)and what did the speaker want to tell us? In this way, you may understand the passage better.
    Josh:  It’s important for you to remember some important facts. for example, if the passage is a science report , you should try to remember its results and how the scientists got them.

    Do you want to live a happier, less stressful life? Try laughing for no reason at all. That’s how thousands of people start their day at Laughter Clubs around the world — and many doctors now think that having a good laugh might be one of the best ways to stay healthy.

    The first Laughter Club was started in Mumbai, India, in 1995 by Dr. Madan Kataria. “Young children laugh about 300 times a day. Adults laugh between 7 and 15 times a day,” says Dr. Kataria, “Everyone’s naturally good at laughing. We want people to feel happy with their lives.” There are now more than 500 Laughter Clubs in India and over 1,300 worldwide.

    Many doctors are also interested in the effects of laughter on our health. According to a 5-year study at the UCLA School of Medicine in California, with laughing there is less stress in the body. Laughter improves our health against illness by about 40%.

    So, what happens at a Laughter Club? I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest — I wasn’t interested in laughing with a group of strangers, and I was worried about looking stupid. Our laughter teacher told us to clap our hands and say “ho ho ho, ha ha ha,” while looking at each other. However, our bodies can’t tell the difference between fake laughter and real laughter, so they still produce the same healthy effects.

    Surprisingly, it works! After ten minutes everybody in the room was laughing for real — and some people just couldn’t stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you’re under stress, then start laughing. You might be very pleased with the results!

    1.The first Laughter Club was started in _____.

    A．Britain            B．America           C．Australia          D．India

    2.The writer felt _____ at the beginning of the class?

    A．surprised         B．pleased           C．nervous           D．stressful

    3.The people in the club began to laugh for real _____?

    A．after ten minutes   B．after ten hours     C．after a few seconds D．after ten days

    4.Which of the following is true according to the passage?

    A．Fake laughter and real laughter are both good for health.

    B．40% of the people in Laughter Clubs are good friends.

    C．Adults laugh more often than children in a day.

    D．Laughing is the best way to prevent illness.

    Children can spend hours a day looking at computer screens and other digital devices. Some eye doctors say this leads to an increase in “computer vision syndrome(电脑视力综合症).”

    Nathan Bonilla-Warford is an optometrist（验光师）in Tampa, Florida. He has seen an increase in problems in children. “A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort, or because their nearsightedness appears to be increasing and they’re worried,” he says.

    Dr. Bonilla-Warford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults. “Even if their eyes start to feel uncomfortable or they start to get a headache, they’re less likely to tell their parents, because they don’t want to have the game or the computer or whatever taken away,” he explains.

    He says another part of the problem is that people blink（眨眼）less often when they use digital devices. He says, “A person who uses an electronic device blinks about one third as much as we normally do in everyday life. And so that can result in the front part of the eye drying and not staying protected like normal.”[来源:Z.xx.k.Com]

    Eye doctors offer suggestions like following which is known as the 20/20/20 rule. That means every twenty minutes look away twenty feet or more for at least twenty seconds from whatever device you’re using.

    Other suggestions include putting more distance between you and the device and using good lighting. Of course, another way is to spend less time looking at screens. Many experts say children should spend no more than two hours a day using digital devices—with no screen time for children under two.

    But not all eye doctors have noticed an increase in problems in children. Dr. David Hunter, from Children’s Hospital Boston, has not seen an increase in his practice. “While it is possible to develop fatigue looking at screens for a long period of time, there’s certainly no proof that it actually causes any damage（伤害）to the eyes.” he says.

    1.Which of the following is true according to the passage?

    A．Dr. Bonilla-Warford thinks using computers causes nearsightedness.

    B．People keep their eyes protected against drying by blinking normally.

    C．Children under two can watch TV for less than two hours a day.

    D．Dr. David Hunter says headache causes an increase in eye problems.

    2.What does the underlined word “fatigue” mean?

    A．Interest

    B．Ability

    C．Tiredness.

    D．Difficulty.

    3.What can be the best title for the passage?

    A．Looking at Screen: Two Hours or More

    B．How Can Children Use Their Eyes Properly

    C．Using Digital Devices: Advantages and Disadvantages

    D．How Much Screen Time Is Too Much for Children
